           Summary: Chromium: The NPObjectWrapper class used by V8
                    bindings to wrap the window object is not allocated
                    correctly.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ananta at chromium.org

This is a Chromium only bug. The NPAllocate function in this class should allocate the NPProxyObject
structure. It ends up allocating the NPObectWrapper instance which is wrong.

The getObjectForCall function in this class should return NULL if it fails to find the underlying NPObject.
It currently returns the same object back which could cause a recursive crash.
